+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+The semantic versioning guarantees cover the interface to the substrate runtime which
+includes this pallet as a dependency. This module will also add storage migrations whenever
+changes require it. Stability with regard to offchain tooling is explicitly excluded from
+this guarantee: For example adding a new field to an in-storage data structure will require
+changes to frontends to properly display it. However, those changes will still be regarded
+as a minor version bump.
+
+The interface provided to smart contracts will adhere to semver with one exception: Even
+major version bumps will be backwards compatible with regard to already deployed contracts.
+In other words: Upgrading this pallet will not break pre-existing contracts.
